Trait TryClone 

pub trait TryClone: Sized {
    type Error;

    // Required method
    fn try_clone(&self) -> Result<Self, Self::Error>;

    // Provided method
    fn try_clone_from(&mut self, source: &Self) -> Result<(), Self::Error> { ... }
}

A fallible variant of Clone.

this trait is intended for types where cloning can fail, for example due to allocation failures, resource limits, or external constraints.

Unlike Clone, the cloning operation returns a Result with an associated error type.

Required Associated Types

type Error

The error type returned when cloning fails.

Required Methods

fn try_clone(&self) -> Result<Self, Self::Error>

Tries to create a duplicate of the value.

Errors

Returns Error if cloning fails.

Provided Methods

fn try_clone_from(&mut self, source: &Self) -> Result<(), Self::Error>

Performs copy-assignment from source. a.clone_from(&b) is equivalent to a = b.clone() in functionality, but can be overridden to reuse the resources of a to avoid unnecessary allocations.

Errors

Returns Error if cloning fails.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
